Beginning soon after NPP launch (October 25, 2011) VIIRS NOAA CoastWatch will produce L2 and L3 NPP ocean color products at native 750m resolution for use in marine ecosystem applications such as harmful algal bloom forecasting, water quality monitoring, and integrated ecosystem assessments. NOAA will acquire and store SDR and EDR data from the Interface Data Processing Segment (IDPS) and operate experimental L1 to L2 processing systems to create derivative products from nLw and chlorophyll retrievals, also included will be daily chlorophyll anomalies, global Emiliana huxleyi presence maps and chlorophyll fronts. To meet user product quality requirements NOAA will execute quality assurance protocols using contemporaneous observations from heritage sensors (MODIS, MERIS) as available on orbit, as well as multi-year science climatology products produced globally at reduced resolution by NASA’s Ocean Biology Processing Group (OBPG). Phase One of this quality assessment model will make use of OBPG’s reprocessed ocean color data as a 'reference baseline' for initial quality assessments of VIIRS data products generated by CoastWatch. Eventually, Phase Two of the quality assessment model will involve validation of NOAA generated products against in-situ data collected at various sites including at the MOBY site in Hawaii. The experimental processing system described above will be transferred to NOAA operations in 2014. NOAA generated VIIRS data and products including quality assessment results will be openly available via NOAA CoastWatch and via ftp access to operational users.
